⚠ Always shut down the main power supply before opening the electrical control box.
3.5 Initial start-up
Start-up procedure - After installation is complete, follow these steps:
- Rotate the fans by hand to verify that they can turn freely by hand, and that the turbine is correctly affixed to the motor shaft.
- Ensure that the unit is connected correctly to the main power supply (see the wiring diagram in the appendix).
- Activate the filtration pump.
- Verify that all water valves are open and that the water flows toward the unit before switching on the heating or cooling mode.
- Verify that the drainage hose is correctly affixed and that it causes no obstructions.
- Activate the unit power supply, then press the On/Off button <0xE2><0x97><0x89> on the control panel.
- Make sure the alarm or lock symbols are not displayed. If need be, see the trouble-shooting guide (see § 6.4).
- Set the water flow using the by-pass valve (see § 3.6 and 2.1), as provided for by each model, to obtain an Entry/Exit temperature of 2°C.
- After running for several minutes, verify that the air exiting the unit is cool (between 5 and 10°).
- With the unit operating, turn off the filter pump. The unit should automatically turn off and display error code E03 (See § 6.4).
- Allow the unit and the pool pump to run 24 hours per day until the desired water temperature has been reached. When the set water inlet temperature is reached, the unit will turn off. It will automatically restart (as long as the pool pump is running) if the pool temperature is at least 0.5°C below the set temperature.
Water flow switch - The unit is equipped with a flow switch that turns on the heat pump when the pool filtration pump is running, and deactivates it when the filtration pump is out of order. If the water is low, the E03 alarm code will appear on the regulator (See § 6.4).
Time delay - The unit is equipped with a time delay of 3 minutes in order to protect the control circuit components, to eliminate restart cycling and contactor chatter. Thanks to this time delay, the unit automatically restarts approximately 3 minutes after each control circuit interruption. Even a brief power interruption will activate the restart time delay.
3.6 Water flow setting
With the water entry and exit valves being open, adjust the by-pass valve in order to obtain a difference of 2°C between the inflow and outflow temperature (see principle diagram § 3.1). You can verify the switch by seeing the entry/exit temperatures directly on the control panel.

5. Maintenance and Winterising
5.1 Maintenance
These maintenance operations must be carried out once per year in order to guarantee the longevity and the good working condition of the heat pump.
- Clean the coil with the help of a soft brush or jet of air or water (⚠ never use a high pressure cleaner).
- Verify that the drains flow well.
- Verify the tightening of the hydraulic and electrical connections.
- Verify the hydraulic sealing of the condenser.
- Have the leak-tightness of the cooling circuit to the leak detector checked by an accredited professional.
⚠ Before any maintenance operation, the heating pump must be disconnected from any electrical current source. The maintenance operations must only be carried out by personnel that is qualified and authorised to handle liquid refrigerants.
5.2 Winterising
- Put the heat pump in “OFF” mode.
- Cut the power supply to the heat pump.
- Empty the condenser with the help of the drain to avoid any risk of deterioration (high risk of freezing).
- Close the by-pass valve and unscrew the entry/exit connection unions.
- Eliminate the maximum amount of residual stagnant water from the condenser with the help of an air gun.
- Close the water entry and exit areas of the heating pump to avoid introducing foreign bodies.
- Cover the heating pump with a dedicated winterising case.
⚠ Any damage caused by poor winterising maintenance will lead to cancellation of the warranty.

6.4 Troubleshooting guide
⚠ Certain operations must be carried out by an authorized technician.
If a fault occurs on the heat pump ⚠ appears in the top left-hand corner of the screen. Refer to following table.
Error Codes and Descriptions:
| Problem | Error codes | Description | Solution |
|---|---|---|---|
| Water inlet sensor fault | P01 | The sensor is open or has short-circuited. | Verify the CN21/RES1 connectors on the board and the extension connector or replace the sensor. |
| Water outlet sensor fault | P02 | Verify the N22/RES2 connectors on the board and the extension connector or replace the sensor. | |
| Outside temperature sensor fault | P04 | The sensor is open or has short-circuited. | Verify the CN12/PH connectors on the board and the extension connector or replace the sensor. |
| De-icing sensor fault | P05 | Verify the CN8/OPT connectors on the board and the extension connector or replace the sensor. | |
| Compressor aspiration sensor select | P07 | Verify the CN7/OAT connectors on the board and the extension connector or replace the sensor. | |
| Compressor discharge sensor fault | P081 | Verify the CN9/OHT connectors on the board and the extension connector or replace the sensor. | |
| High pressure protection | E01 | The sensor is open or has short-circuited. | Verify the CN30/HP connectors on the card or replace the sensor. Check the water flow. Check the water flow detector. Check the valve opening. Check the by-pass. Check the evaporator is not clogged. Water temperature too hot. Incondensable problem after maintenance, empty and evacuate the cooling circuit. Fluid load too high, remove fluid into a liquid bottle. |
| Low pressure protection | E02 | The sensor is open or has short-circuited. | Check the Al/D103 connections on the card or replace the sensor. Large coolant leak, search for the leak with the detector. Air flow too low, check the ventilator rotation speed. Check the evaporator is not clogged, clean its surface. |
| Flow sensor fault | E03 | The sensor is open or has short-circuited. | Check the Al/D102 connections on the card or replace the sensor. Lack of water, check the filtration pump operation. Check the stop valve opening. Check the by-pass adjustment. |
| Input/Output temperature difference > 13°C | E06 | Applicable in Cold mode only | Lack of water, check the filtration pump operation. Check the stop valve opening. Check the by-pass adjustment. |
| Antifreeze protection Cold mode | E07 | Water output temperature < 4°C | Stop the heat pump, empty the condenser risk of freezing. |
| Communication problem | E08 | No communication between the printed circuit board and the user interface | Check the connectors - see the wiring diagram. |
| Level 1 antifreeze protection | E19 | 2°< Water temperature < 4° and Air temperature < 0° | Stop heat pump operation, empty the condenser to avoid freezing, by default the heat pump starts the filtration pump to avoid icing over. |
| Level 2 antifreeze protection | E29 | Water temperature < 2° and Air temperature < 0° | Stop heat pump operation, empty the condenser to avoid freezing, by default the heat pump starts the filtration pump and the heat pump to avoid icing over. |
| Fan motor fault | F031 | Motor jammed or faulty connection | Check free rotation; check CN97/DC connectors; replace the motor. |
| Fan motor fault | F051 | Faulty connection | Check the DCFAN/CN97 connector; replace the motor. |
| Exterior temperature too low | TP | Operating limit reached | Stop the heat pump. |
